I've heard about gold coins in Farming Simulator 15 but I have no idea what they are for. Does anyone know what they are for and how I get them?

Gold Coins are used as an in game collectible, on the Bjornholm map. According to the farming simulator wiki, collecting all 100 coins, and throwing them down a well, rewards the player with "200,000 litres of each commodity".
Coronus has provided a link to a gamepressure guide, where all the coins are plotted out on a map, and detailed further for the purpose of collection.
